The natural aquatic ecosystems are being significantly impacted by the discharge of wastewater containing harmful heavy metals from the industrial sector without proper treatment of contaminated water. As a result, harmful heavy metals collected in various aquatic animal organs, such as fish tissues or organ systems, disrupting their physiological pathways and lowering their rate of development and reproduction. Bioaccumulation is a sustainable method for addressing heavy metal toxicity in polluted aquatic environments. Additionally, by modifying the harmful effects of certain heavy metals, bioremediation aids in improving the physical conditions of fish. Additionally, it contributes to the productivity of aquatic ecosystems by using the proper bioremediation techniques, which can significantly recycle water to reduce water waste and significantly reduce bio-contaminants by decomposing organic matter and increasing environmental biosafety.
